Referring to Figure 5y of the; drawings, the forward coupler is similarin construction as the forward coupler'illustrated by Figures l and 9,and vis referredV to generally by the reference character 75. The rearcoupler consists of a rectangular bar 76, having each sideedge providedwith a series of angle shaped slots. The slots at one side edge areindicated at 77, and the slots at the'other side edge by the referenceAcharacter 7 8. The` j slots 77, are oppositely disposedY with respectto the slots 78. The lower end ofthe barv 77,is reduced, as indicatedat`79, and is re-` movably connected by the securing device 80,to` theend 81, ofa hack saw blade v82.
